SCAFFOLD --App1ication filed July 12,

To all whom it may concern:

Be it known thatI, ARCHIBALD MoLAnnN, a citizen of theUnited States, and a resident of ClevelandHeights, county of Guyahoga, and State of Ohio, have invented a new and useful Improvement in Scaffold Brackets, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The present invention relates toafolding scaffold bracket which may be'applied to the sidewall of a frame structure by merely hooking one end of the bracket around one of the-uprights, the entirebracket being so arranged asto maintain itselfsecurely in position without danger of slipping and without being secured to the building by means ofnailsor-spikes. Thebracket consists essentially ofa main'bar' with the hook on one end adapted to'engage around one of the uprights, and-to this bar is pivoted asupporting member adapted to have its free end-rest against the wall of a structure so as to support the bracket. In addition to this there-is a triangular'bracing member adapted to engage with the main bar so as to hold-the hook-iniplace around the studding, and this member also-is adapted to prevent the bracket from fpivoting around thehook. To the accomplishment of the foregoing and related ends, said invention, then, consists ofthe means hereinafter fully described andparti'cularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of theinvention may be used.

In said annexed drawing Fig. 1'is='a perspective view of my improved scaffold bracket as applied to a portion of a building wall; Fig. 2 is a side'elev-ational view of the bracket when folded; Fig. 3 isa sectional view on the line 33 in Fig. 1; Fig. this a sectional view on the line 4. 4: in Fig. 1; and Fig. 5 is a sectional View on the line '55'in Fig. 1.

The present scaffold bracket consists essentially of a main-bar 1 having -a hook 2 formed at-the rear end of a size to engage aroundthensual two inch upright or studding 3 ofthe wall '4 of-a house or other BRACKET.

building, and this bar has at its other end a slight upward projection 5 so as to prevent the scaffold board 30 (shown in dotted lines) from slipping off the front of the bracket. Secured near the forward end of the bar is a supporting member 6 formed of inverted T-shape in cross section, and this member is pivotally attached by means of a suitable bolt or-rivet 7 to the main supporting bar and has its attaching end curved so as to'engage with the supporting bar at substantially right angles thereto. This attached end of the supporting member has the horizontal flange 8 cut away so as to limit the downward pivotal movement of the member and thus act as a stop anda support in addition to the bolt which holds it in place. At the other. end the vertical flange 9 of the T-shaped member is cut away and the horizontal flange is bent downwardly so-as to engage withits fiat surface 10 the boards 17 of the wall from which the bracket is supported.

link llhavinga hook 12 at its upper end which engages over the main bar and spaces the rear of the supportlng member at the correct distance below the bar.

To correctly position the bracket in place and to prevent sidewise or pivotal movement around the hook, the bracket is providedwith alocking triangular brace member 13 formed of strap metal, the two ends latforining the apex of the triangle and being ipivotally secured to the main bar by means of a bolt or rivet15, and this member has the base 16 of the triangle parallel to the boards 17 of the wall on which the bracket-is to be supported and closely adjacent to-such boards, the =member being spacedwith' its base at such a distancefrom the'hookedend as to allow the base to clear the usual siding boards which are applied over thestudding. In order to hold this triangular brace in position, the base member is-bent at its central vpointto provide a locking recessQO which'fits over the main bar, as best shown-in Fig. 5,'-and thusvprevents sidewise twisting of the triangular member so as-to hold it always in place with the base parallel'to the w'allboards.

When not in use the bracketmaybe'foldedup-into thevpositionbest shown in-Fig.'2, in-which position it will "be seen that the is folded down parallel with and adjacent to the vertical flange ot' the supporting memher.

In using the present bracket, the triangular brace member is moved upwardly so as to allow the main bar to be hooked over one of the uprights, and the brace is then moved into its locking position and the supporting member is dropped until it is stopped by the hooked link so that the lower end rests flat against the boards of the wall. The bracket is then held securely in place and does not need to be nailed or in any othu' way secured, and it may be easily remo ved when d eired.

By use of the triangular inverted T- shaped supporting member, the point of attachment between the supporting member and the main bar is made sate by the cutting away of the horizontal tlange so as to provide a stop at this point to limit the pivotal movement of the supporting member away from the main bar. All of the parts of the present bracket are simple to manufacture and easy to assemble, and the entire bracket is easily mounted in place and taken down or moved when desired.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention 1. In a scaffold bracket, the combination of a main supporting bar provided with a hook at the inner end adapted to engage an upright, a supporting member pivotally connected to said main bar near the end opposite to said hook and having limited an gular movement away trom said bar, and a triangular brace member pivoted to said bar and with its base parallel to the wall boards and provided with means for engaging said bar to prevent relative sidewise movement between said bar and said brace.
